Android Question Firebase Push Notification - integration with ASP.NET

[Alex_197]

Hi all.

I want to integrate the Firebase Push Notification with my asp,net website. But from what I read so far is that the token generated by B4J GetTokenValue is valid for 1 hour only.
So if I start B4J sending tool and copy the token string from there and use it in my asp.net this token will expire in 1 hour.

Is there any options to either convert GetTokenValue to vb.net /c# or to pass some parameters into B4J project?

 

[Erel]

or to pass some parameters into B4J project?

What exactly do you mean?

or to pass some parameters into B4J project?

The given parameters are in Args.

Sub AppStart (Form1 As Form, Args() As String)
...
End sub

I can´t help you with code in vb.net /c# to start an app and give parameters.

In Delphi i use

    OpenProgram2('"C:\Java\jdk-11.0.1\bin\javaw.exe"',tempdir,'--module-path C:\Java\jdk-11.0.1\javafx\lib --add-modules ALL-MODULE-PATH -jar \\192.168.2.252\jars\UnternehmerErklaerung.jar '+IntToStr(abnr)+'');

where IntToStr(abnr) is ust the string-interpretion of abnr (int).

You can add more parameters.

OpenProgram2 is just a helper-sub around ShellExecute

procedure OpenProgram2(prog, path, params: string);
var
  c, p, dir: array[0..800] of Char;
begin
  StrPCopy(c, prog);
  StrPCopy(p, params);
  StrPCopy(dir, path);
  ShellExecute(0, 'open', c, p, dir, SW_NORMAL);
end;

Thanks, That's what I need.

I'm asking - is it possible to convert into C# or VB/NET this code

Private Sub GetTokenValue (FilePath As String) As String
    Dim GoogleCredentials As JavaObject
    GoogleCredentials.InitializeStatic("com.google.auth.oauth2.GoogleCredentials")
    Dim Credentials As JavaObject = GoogleCredentials.RunMethodJO("fromStream", Array(File.OpenInput(FilePath, ""))) _
        .RunMethod("createScoped", Array(Array As String("https://www.googleapis.com/auth/firebase.messaging")))
    Credentials.RunMethod("refreshIfExpired", Null)
    Return Credentials.RunMethodJO("getAccessToken", Null).RunMethod("getTokenValue", Null)
End Sub

I need to send messages from my asp.net website.

I guess that it is possible. You need to go over Google documentation and find whether they provide asp.net SDK and follow their instructions.

Thank you. I will check it, But what if they don't have asp.net SDK?

 

[Erel]

Then use B4J.

 

[Erel]

You can also create a B4J console app and run it from your server whenever you need to send a message.

Thank you. Good idea.
